Abstract

A quasi-optical mode converter in the form of a corrugated horn has been designed through numerical simulations, manufactured and experimentally measured for application in W-band gyro-devices. This horn converts a cylindrica TE11 mode into a free space TEM00 mode in a frequency band of 84-104 GHz with a reflection better than -30 dB, a Gaussian coupling efficiency of similar to 98% and directivity of 26.6 dB at 95 GHz. The small beam waist makes such a horn ideal for use with a depressed collector system. The measured results are in excellent agreement with the numerical simulations.
